By now, you’d be well attuned to how it works. You spray it on when your strands are looking drab and it mops up enough oil to let you live another day, in which you don’t have to go through the rigmarole of washing and drying your hair (some have even called it one of the greatest beauty inventions of our time – most of the whimn team included).

And you’ll be pleasantly surprised to hear that not only does it mop up greasy roots (as well as adding texture and volume without the frizz) but it also saves a bunch of water.

Recent research has found how much water can be spared with a simple switch from wet to dry – and it’s a hell of a lot more than you’d think.

According to Klorane, by replacing just one wet hair wash with an application of dry shampoo each week can help save up to 500 litres of h20 per year. Yep.

For everyday hair washers, 3,500 litres of water can be poured down the drain each year. With water scarcity an ongoing issue and even further water restrictions flagged for Australians as summer approaches, we are all no doubt looking for ways to save on water waste and this is a good place to start.
